Article - Comparison of Arsenic and Boron Limits in Drinking Water According to WHO and EPA

The presence of arsenic and boron in drinking water represents a significant public health challenge, particularly in arid regions where groundwater is the primary source of supply. International organizations such as the World Health Organization (WHO) and the United States Environmental Protection Agency (EPA) have established guideline values and regulatory standards to safeguard human health. This study compares the limits set by both institutions for arsenic and boron in drinking water. A documentary review was conducted, focusing on the most recent standards. Results reveal that the WHO guideline value for arsenic is 0.01 mg/L, aligned with the EPA maximum contaminant level (MCL), while boron presents notable differences: 2.4 mg/L in WHO guidelines versus 2.0 mg/L under EPA health advisories. These discrepancies have practical implications for regions with naturally elevated arsenic and boron concentrations, such as southern Peru. The study underscores the importance of harmonizing regulatory frameworks to ensure global consistency in health protection.
